FAN ATTACHMENT FOR ELEVATOR-CARS.

SPECIFICATION forming part of Letters Patent No. 350,95', dated October-19, 1856. Application filed June 2, 1886. Serial No. 203,932. (X0 model.)

To all whom, it may concern:

Be it known that I, FRANCIS Sassn, a citizen of the United States, residing at Vashington city, in the District of Columbia, have invented certain new and useful Improvements in Fan Attachments for Elevator Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to improvementsin fan attachments for elevator-cars; and my said invention consists of a rotary fan secured, preferably, to the top of the car for creating a current of air within the same, which is automatically operated by the movement of the car asit passes up and down the elevator-shaft through the medium of a cord suspended in said eleva tor-shaft engaging a pulley on the fan-shaft.

In many elevator-cars the air is very close and uncomfortably warm, owing to the lack of ventilation therein. Especially is this the case in warm weather, and in such cars as require a lighted gas-jet, because of the heat and unpleasant odors generated thereby.

' The object, therefore, of my invention is to overcome these objections, and to accomplish this I proceed as follows, particular reference now being had to the accompanying drawings for a better understanding of the details of construction and arrangement of the parts composing my invention, whereby to accomplish the desired result, wherein- Figure 1 represents asectional side elevation of an elevator-car suspended in its shaft and as supplied with an air-fan in accordance with my invention. Fig. 2 is a detailed view, on an enlarged scale,of the fan-shaft and its housings, boxes, and bearings.

A is the elevator-car,of the usual construction, suspended by the cables B within the elevator-shaft C. At the top of this car is arranged the air-fan,which may be composed of a series of horizontally rotating blades, F, whose shanks f are fitted into sockets a, formed in a head, 12, secured upon the end of a short shaft, S. By this means the blades are rendered adjustable, so that their angularity may be changed, as desired, to create a more or less agitation or current otair in the car, and said blades, when so set, are held bya pinch-screw, as at g. The shaft- S has upon its outer end a pulley, P,and it is secured in position, preferably in the roof of the car, by a bearing, D, having flange d, by which it is secured to the outside ofthc top of the car.

' E is a sleeve placed 11 pen the fan-shaft, whose internal diameter is slightly greater than the diameter of the fan-shaft, to prevent friction between these parts, and at the bottom of this sleeve is a stuffing-box, K,which forms a bearing for the lower end of the fan-shaft. The object of the sleeve E is to support the fanshaft, provide a proper bearing for the lower end of the same, and prevent lateral displacement, and, in addition to this, the stutlingbox acts as a drip cupto receive surplus oil which may escape from the upper bearing and pass down the fan-shaft, so that the dropping into the car of said oil is revented. ielow this stuflingbox K, and upon the top ofihe bearing-D on the fan-shaft, aresecured collars 1 and 2, having pinch or set screws, as shown,whicl1 prevent vertical displacement of the said fanshaft, and through the top collar, 1, is an oilhole, 11., iorsumilyi ng the cup iin the head of the bearing 1). This constitutes the fan, its shaft, and bearings therefor, which are applied to the top central portion of the car. Now, to supply the mcans for operating said fan, I proceed as follows, to wit:

Secured either at the top ,or bottom of the elevator-shaft is a saslrcord, G, which, after passing around a guide or idle pulley, H, passes around the pulley P on the fan-shaft, and then back over a second guide or idle pulley, I, placed opposite the one H and secured upon the top outer edge of the car. The cord then continues on to the other extremity of the elevator shaft, where it is secured to one end of a spiral spring, J, whose other end is fastened to the bottom or top, as the case may be, of the shaft. The object of this spring is to maintain the proper tension upon the cord, so as to prevent slack in the same, and thereby 5 insure the continuous and regular working of the fan.

Instead of a horizontally-revolving fan arranged within the car, as here shown, being employed, any other form of fan may be usedsuch, for instance, as a fan similar to those used in fanning-millswhich may be secured upon the outside of the car,and either upon the top or side thereof, and communicate with the car by suitable openings, and it may operate either as a blast or suction, as desired, or found to accomplish the best results.

The operation is as follows: The cord being fixed, as the car moves up and down, the puland instead of a spring being applied to the end of said cord, a weight may be used in place thereof, and a spring may be applied to both ends of the cord.

Having thus fully described my invention, what I claim as new therein, and desire to secure by Letters Patent of the United States, is as follows, viz:

1. The co1nbination,with an elevator-car, of a fan applied to said car, cord suspended at top and bottom of the elevator-shaft, and suitable connections whereby the fan is automatically operated by the movement of said car as it passes up and down the elevator-shaft.

2. The combination,with an elevator-car, of a fan applied to said car, a cord suspended from top to bottom of the elevator-shaft for operating said fan, and a suitable tension applied to one or both ends of said cord, substantially as and for the purposes described and shown.

3. The combination,with an elevator-ear, of a fan applied to said car, a cord suspended from top to bottom of the elevator-shaft for operating said fan, and suitable guide-pulleys for said cord, for the purposes specified.

at. The combination,with the fan-shaft S, of r the sleeve E, depending from the roof of the e1evator-car,bearing D,secured upon said roof, stufiing-box K at the lower end of the sleeve, and collars 1 2, secured at each extremity of the fanshaft, substantially as described and shown, for the purposes specified.

5. The combinatiomwith an elevator-car,of a

fan, fan-shaft having a driving-pul'ley-thereon, cordfor operating said fan secured at the top and bottom of the elevator-shaft, guide-pulleys for the cord, and suitable tension at one or both ends of said cord, substantially as described and shown, for the purposes specified. I 1 FRANCIS SASSE.
